| Using Sidekiq for Active Job and getting ActiveJob::DeserializationError Posted: 20 Aug 2016 08:20 AM PDT I'm trying to use Sidekiq to run the below job. The job performs fine when not queued (perform_now) but fails when called as (perform_later), which uses Sidekiq. AddEmployeesToRoomJob.perform_now room ## works fine AddEmployeesToRoomJob.perform_later room ## breaks in Sidekiq
Error: AddEmployeesToRoomJob JID-da24b13f405b1ece1212bbd5 INFO: fail: 0.003 sec 2016-08-20T14:57:16.645Z 19456 TID-owmym5fbk WARN: {"class":"ActiveJob::QueueAdapters::SidekiqAdapter::JobWrapper","wrapped" :"AddEmployeesToRoomJob","queue":"default","args": [{"job_class":"AddEmployeesToRoomJob","job_id":"0ba5bd30-e281-49a7-a93f- 6e50445183ac","queue_name":"default","priority":null,"arguments": [{"_aj_globalid":"gid://dragonfly/Room/1"}],"locale":"en"}],"retry":true, "jid":"da24b13f405b1ece1212bbd5","created_at":1471704675.739077,"enqueued _at":1471705036.6406531,"error_message":"Error while trying to deserialize arguments: Couldn't find Room with 'id'=1","error_class":"ActiveJob::DeserializationError","failed_at":14717 04675.946183,"retry_count":4,"retried_at":1471705036.644416} 2016-08-20T14:57:16.645Z 19456 TID-owmym5fbk WARN: ActiveJob::DeserializationError: Error while trying to deserialize arguments: Couldn't find Room with 'id'=1 2016-08-20T14:57:16.645Z 19456 TID-owmym5fbk WARN: /Users/tamlyn/.rvm/gems/ruby-2.2.3/gems/activerecord- 5.0.0.1/lib/active_record/relation/finder_methods.rb:357:in `raise_record_not_found_exception!'
My Job class AddEmployeesToRoomJob < ApplicationJob queue_as :default def perform(room) employees = Employee.all if employees.length > 0 employees.each do |employee| UserRoom.create(user: employee, room: room) end end end end
My Thoughts I don't understand why it can't find the room which I'm passing into the perform method. It's as though it somehow loses that variable in the queueifying / JSONifying of the job? The Sidekiq docs say "Unfortunately this means that if the [Room] record is deleted after the job is enqueued but before the perform method is called, exception handling is different." They suggest a workaround but I don't see how that would help me: rescue_from ActiveJob::DeserializationError do |exception| # handle a deleted user record end
Thanks in advance for any help! |
| Access-Control-Allow-Oirigin on a single Rails route Posted: 20 Aug 2016 08:11 AM PDT In my Rails app, I'm building a feature that allows users to embed data from the app on other sites using a Javascript snippet. My Javascript snippet makes a GET request to a route in my rails app that returns raw JSON. When snippet and the JSON share the same domain, everything works well, but I'm running into CORS issues when I embed the snippet on another site. Using the solution I found here, I've begun configuring my Rails app for CORS. In my application_controller.rb: before_filter :add_allow_credentials_headers def add_allow_credentials_headers response.headers['Access-Control-Allow-Origin'] = request.headers['Origin'] || '*' response.headers['Access-Control-Allow-Credentials'] = 'true' end def options head :status => 200, :'Access-Control-Allow-Headers' => 'accept, content-type' end
In my routes.rb: get 'embed_json' => 'application#options', :via => [:options]
However, when I hit the above route in my browser, the app no longer returns the JSON object—just a blank screen. There seem to be a number of conflicting approaches on how best to handle CORS on a single Rails route. Is there a "Rails way" to handle this requirement? |
| Publish method doesn't work properly Posted: 20 Aug 2016 08:22 AM PDT I have an Entry model with a boolean column published, which is set to false by default. I wrote the following method in the model: def self.publish self.update(published: true) end
and in my controller I have def publish @entry = Entry.find(params[:id] @entry.publish redirect_to entries_path end
(I thought to make it similar to the calling of destroy method in the model). Finally, in my view I have this: <%= link_to "Publish", entries_path, method: :publish %>
But when I click the link, the request is processed by create method and returns me the following error: ActionController::ParameterMissing in Multiflora::EntriesController#create param is missing or the value is empty: entry

| InvalidAuthenticityToken errors in mobile Posted: 20 Aug 2016 08:10 AM PDT I have read multiple questions and answers here on StackOverflow about InvalidAuthenticityToken and protect_from_forgery but get none the wiser. I have a website that get hundreds of these errors every day. They seem to be mainly (only?) from mobile but I have only verified that through samples. I understand why there is an AuthenticityToken and the need for adding <%= csrf_meta_tags %>
in the application.html (which I have) as well as having protect_from_forgery in the application controller. I have both the csrf_meta_tags and: protect_from_forgery with: :exception
in my Application controller, as is default. I realize I can "solve" the problem by removing protect_from_forgery but that would make me vulnerable for CSRF-attacks so that is not really a solution, is it? I could add an "except" for protect_from_forgery for the form posts that take place but that would leave me just as vulnerable, right? Edit: I tried accessing the form with my mobile with cookies disabled and experienced a 422 error. Couldn't get it to cause the exception though. Adding an exception for my "result" function removed that, but that makes it vulnerable I guess? I am now in a position where I can't have it since it causes error for hundreds of users per day and I can't remove it because I am afraid that it will make my website vulnerable for hacks. So, what can I do? Is there a decent middle ground? Is there any way I can alter the protect_from_forgery and still feel fairly confident that I will not have my database destroyed by hackers? I am not using any API for the site and all of the errors come from the same type of form. I understand there is a javascript part to this problem but not really how I can use that information to solve the problem. Thanks in advance!

| Cocoon gem inside a table in rails Posted: 20 Aug 2016 08:04 AM PDT I'm busy with a invoicing application and i'm trying to put a nested form from the cocoon gem inside a <tbody></tbody>. The nested form is working perfectly but it doesn't show up in the <tbody></tbody> but at some random place above the table head. I think it's because you can't have <div class=nested-fields></div> inside the table body but i'm not sure how to do it differently. 
i have this in my invoices/_form.html.erb : <div class="row"> <div class="col-sm-12"> <table class="table table-striped"> <thead> <tr> <th class="hidden-480"> Hoeveelheid </th> <th class="hidden-480"> Beschrijving </th> <th class="hidden-480"> Bedrag </th> <th class="hidden-480"> Totaal </th> <th class="hidden-480"> Btw(%) </th> </tr> </thead> <tbody> <%= f.fields_for :products do |product| %> <%= render 'product_fields', f: product %> <%= link_to_add_association 'Item toevoegen', f, :products, class: 'btn btn-primary btn-success' %> <% end %> </tbody> </table> </div> </div>
invoices/_product_fields.html.erb <div class="nested-fields"> <tr> <td> <%= f.text_field :quantity %> </td> <td> <%= f.text_area :description %> </td> <td> <%= f.number_field :unitprice %> </td> <td> €200 </td> <td> <%= f.select(:btw, [[' 21%', 21, title: '21%'],[' 6%', 6, title: '6%'], [' 0%', 0, title: '0%']]) %> </td> </tr> <%= link_to_remove_association 'x', f, class: 'btn btn-primary btn-danger' %> </div>
Any idea what's going on? Help would be much appreciated! |

It looks at situations like two let(ind and ind2) coudn't work together.

| Handle post request in backbone Posted: 20 Aug 2016 06:40 AM PDT New to backbone, I am building a backbone application which uses rails APIs. This application involves PayU integration. I am able to send POST parameters to PayU (via submitting a hidden form) to initiate the gateway. Following are the code snippets i had used: <form id = "payu_post_form" action = "{{payu_post_form_url}}" method="POST"> <input type="hidden" name="key"/> <input type="hidden" name="txnid"/> <input type="hidden" name="amount"/> <input type="hidden" name="productinfo"/> <input type="hidden" name="firstname"/> <input type="hidden" name="email"/> <input type="hidden" name="phone"/> <input type="hidden" name="hash"/> <input type="hidden" name="service_provider"/> <input type="hidden" name="surl"/> <input type="hidden" name="furl"/> </form> $.ajax({ url: URL['buyCourse'](course_id), type: 'GET', crossDomain: true, xhrFields: { withCredentials: true }, beforeSend: function(xhr) { xhr.setRequestHeader('X-CSRF-Token', $('meta[name="csrf-token"]').attr('content')); }, success: function(res, status, xhr){ /////// setting values to hidden tags of payu_post_form _.each(res, function(value, key, payu_payload){ $('input[name="'+key+'"]').attr('value', value); }); $('input[name="surl"]').attr('value', CONSTANTS.payu_success_url); $('input[name="furl"]').attr('value', CONSTANTS.payu_failure_url); $('form#payu_post_form').submit(); }, error: function(res, status){ alert(res.message); } }).complete( function(){ });
But i am stuck capturing the response from PayU in my Backbone application, as PayU send response parameters via POST request that i need to capture in my backbone application and then further send to rails API. How backbone route handled POST requests? Is there anyway i could do that? If not, then kindly let me know a different approach to implement this. Any help will be appreciated. |
| Paperclip 5.1.0 - undefined method [] for nil after update Posted: 20 Aug 2016 05:45 AM PDT I am using paperclip to store images. After updating to 5.1.0 (released tonight) I get the following error: undefined method `[]' for nil:NilClass
My code in the view is this: <%= @company.pic1.url(:large)%>
A change in 5.1.0 is the switch to leave s3_protocol as an empty string, if not set in the app: Is it possible to configure Paperclip to produce HTTPS urls? Following the advice there, I tried setting that string in the model to "http", "https" and :https, but didnt solve the problem. What could be wrong? This is my model: has_attached_file :pic1, :styles => { :large => "1000x600", :mid => "400x160", :thumb => "120x80>" }, :default_url => "https://s3.eu-central-1.amazonaws.com/server.assets/images/missing/image_missing_:style.png", :storage => :s3, :s3_credentials => APP_CONFIG["s3"], :path => ":class/:attachment/:style/:id.:extension", :s3_region => "eu-central-1", :s3_protocol => "http"

| LoadError in Controller#index Posted: 20 Aug 2016 08:03 AM PDT I created a polymorphic relation in a book reviewing app that I am writing. My app has the nested models: Piece >> Section >> Subsection >> Subsubsection, and I have created a model which belongs to all of these called KeyConcept, my intention being that each of these can have a key concept. I am getting an error that I don't understand when trying to display the index action of the keyconcepts controller. I think it might be due to a naming conflict but I don't have enough experience to understand it. the error I am getting looks like this: Unable to autoload constant KeyConceptsController, expected /home/david/Documents/Learning/StuddyBuddy/app/controllers/key_concepts_controller.rb to define it else require_or_load(expanded, qualified_name) raise LoadError, "Unable to autoload constant #{qualified_name}, expected #{file_path} to define it" unless from_mod.const_defined?(const_name, false) return from_mod.const_get(const_name) end elsif mod = autoload_module!(from_mod, const_name, qualified_name, path_suffix)

the link comes from the show action of the parent Piece model here: <% @piece.key_concepts.each do |concept| %> <li> <%= link_to concept.definition, [@piece, @keyconcept] %> <!-- we didn't use #piece_key_concept_path(@piece, @keyconcept), class: 'section_name' and it worked --> </li>
How do I link to the keyconcepts "show" action by the way? I havent been able to so i just linked to the index action :/ So the routes.rb file looks like this: resources :pieces do resources :sections do resources :subsections do resources :subsubsections end end resources :links end resources :pieces, :sections, :subsections, :subsubsections do resources :connections, only: [:index, :new, :edit, :update, :destroy, :create] resources :keyconcepts, only: [:index, :new, :edit, :update, :destroy, :create, :show] end

| How to compare arrays inside an array with each other in ruby? Posted: 20 Aug 2016 06:55 AM PDT [ 1, 1, 3, 5 ] & [ 1, 2, 3 ] #=> [ 1, 3 ] [ 'a', 'b', 'b', 'z' ] & [ 'a', 'b', 'c' ] #=> [ 'a', 'b' ]
I need the intersection of each array with all other arrays within an array. So the array could look like -> a = [[1, 2, 3], [3, 4, 5], [4, 5, 6],[1,"a","b"]] Now I need to compare them with each other and return an array of arrays with the given results from the intersection method. Anyone an idea? I tried the .next operator within a loop, but it is not supported for arrays in ruby 2.3.0 yet. something like: a.each_with_index do |a, i| a.length.times.each_with_index |j| p c[i]& c[i+1](***or c[i].next; end
But that didn't work. |

| What websocket to use with WebRTC on Rails? Posted: 20 Aug 2016 05:12 AM PDT I am trying to implement WebRTC on Rails, which is a tough task because I am new to Rails and web conferencing. I have followed a tutorial on http://www.tutorialspoint.com/webrtc/ but it appears we need a websocket installed for this to work. I tried a few but have been hitting some walls. I then finally tried web-socket-js with which I could actually get the websocket object on the client side but my setup is still having issues getting the websocket server object on the server.js side. Does anyone know what websocket would work best with Rails/WebRTC or is there something fundamental that I am missing from this documentation? |

| Optimize this validation and initialization Posted: 20 Aug 2016 03:45 AM PDT I have a very special solution on a Rails 4.2 website where I have many complicated calculations. The problems I have consider validation and initialization. I create a separate class for each calculation and all look virtually the same way, as can be seen below (code simplified to be easier to overlook). I am out a bit on thin ice here since I have not done anything like this before and some of it is "trial and error programming" but it works. I am using the code in controllers etc using PUT requests like this: C_9.calculate_me(params)
where params could look like this: {"utf8"=>"✓", "_method"=>"put", "authenticity_token"=>"...", "start_date"=>"2016-08-20", "nbr_of_days"=>"90", "commit"=>"Calculate", "controller"=>"calculations", "action"=>"result", "id"=>"9"}
The code class C_9 include ActiveModel::Validations include ValidationFunctions attr_accessor :start_date, :nbr_of_days validates_length_of :start_date, :minimum => 8, :message => "value_is_not_a_proper_date" validates_numericality_of :nbr_of_days, :greater_than => 0, :message => "value_must_be_number_over_zero" validate :validate_buggy_start_date def initialize(params = {}, options = {}) @start_date = params[:start_date] @nbr_of_days = params[:nbr_of_days] end def calculate_me(params) @start_date = @start_date.to_date result_date = @start_date + @nbr_of_days.day end end
Validation functions These are validation functions that are common for many different calculations. def validate_buggy_start_date # Don't know why the validate_start_date will not work for this... errors.add(:start_date, 'value_is_not_a_proper_date') unless validate_date(start_date) end def validate_date(this_date) begin Date.parse(this_date) this_date.to_date rescue proper_date = false else proper_date = true end
end What I need help with The system is working but there are certain issues I need to optimize: Is there any way I can validate a date in ValidationFunction without having to create a new function (like def validate_buggy_start_date) for every date that is named differently. Is there any way I can use the validate_date()-function right away from C_9 (i.e. without having to go through validate_buggy_start_date)? I would like to initialize the parameters and at the same time make sure they are float/string/date etc with for example variable.to_date. I can't, however, since the initialization is done before the validations so it will crash the app. I now solve it by re-establishing them in the calculate_me()-function but it does not feel very DRY. Is there any way around this? For some reason that I cannot understand I need to name the variables exactly like the attribute name, for example @nbr_of_days needs to be named just that. If I name it @day_numbers it will not work (the value will not be set). Why is it so? Is there a smarter way around it? In short, please help me make this functionality smarter and more DRY, if possible! |
| Trying to configure environment variables using fb app_id and app_secret Posted: 20 Aug 2016 06:38 AM PDT I am following rails cast #85 here and the marked correct answer on stackoverflow here. I am trying to use facebook "app_id" and "app_secret" to set as environment variables in rails. my code is: initializers/facebook.rb FACEBOOK_CONFIG = YAML.load_file("#{::Rails.root}/config/facebook.yml")[::Rails.env]
config/facebook.yml development: app_id: abcdefg app_secret: 123456 production: app_id: abcdefg app_secret: 123456
initializers/omniauth.rb OmniAuth.config.logger = Rails.logger Rails.application.config.middleware.use OmniAuth::Builder do provider :facebook, FACEBOOK_CONFIG['abcdefg'], FACEBOOK_CONFIG['123456'], {:client_options => {:ssl => {:ca_file => Rails.root.join("cacert.pem").to_s}}} end
When I set the environment variables in front of the app_id and app_secret ie FACEBOOK_CONFIG when I try login through facebook it returns a "app_id parameter is required" message. So this way is not working. I am wondering if there is some code missing or someone can see something I am doing wrong the environment variables are not being processed through facebook (where they were before without any ENV variables). |

Posted: 20 Aug 2016 02:17 AM PDT I'm new to react-rails, my repo is at https://github.com/yogabread/react_try I'm trying to assign the current_user.id to each micropost, but I don't know how to do it using react. I don't know the proper syntax for doing it from the view by adding hidden input, and building it from the controller @micropost.user_id = current_user.id doesn't work. How can I put hidden fields like the one below in an x.js.jsx file? = f.hidden_field :user_id, value: current_user.id

| Customizing fields with the administrate gem for rails Posted: 20 Aug 2016 01:31 AM PDT I cannot seem to find any documentation on how to modify the administrate gem's default dashboards in order to customize what gets displayed in the index and show pages. Here's my specific goal: - Given that an
Article belongs_to an Author - When I create an Article
- I want to see the Author's last name in the dropdown list for the associated field
- And once saved, I want to see the Author's last name in the Article's index and show pages
Right now, instead, I get a not-so-useful "Author #4" as the record label. Here's the automatically generated dashboard: class ArticleDashboard < Administrate::BaseDashboard ATTRIBUTE_TYPES = { author: Field::BelongsTo, id: Field::Number, title: Field::String, content: Field::Text, created_at: Field::DateTime, updated_at: Field::DateTime, }.freeze [snip] end
The "Customizing Dashboard" documentation page says: Each of the Field types take a different set of options, which are specified through the .with_options class method. So I figure that calling with_options on Field::BelongsTo might be the way to go, but what options are available for that field (or for any other, for that matter)? |

| Rails - return all values for nested-attributes, instead of just the 'pointer' Posted: 20 Aug 2016 12:31 AM PDT So, I've been banging my head against the wall for the past couple of hours trying to get this. Also, I'll change the name of the question when I know the name of the thing below. First question, what is this called? #<Comment:0x007fda3aaeb7c8> which is returned from the database. Secondly, I'm trying to return (render json) a comment that contains child comments. Something like this: [ { id: 1, title:'title', body:'body' }, { "#< Comment:0x007fda3b3517f0>": {}, "#< Comment:0x007fda3b3517f0>": {}, } ]
How do I return the values of those comments? When I puts them in the console it shows their attributes and values, like so: puts comments[0][1] {#<Comment id: 17, body: "Another Reply Test", created_at: "2016-08-20 04:05:16", updated_at: "2016-08-20 04:05:16", parent_id: 13, user_id: 54>=>{}, #<Comment id: 18, body: "Another Reply Test", created_at: "2016-08-20 04:05:16", updated_at: "2016-08-20 04:05:16", parent_id: 13, user_id: 54>=>{}}
but if I try to modify them at all - like to_a or to_json - it just blows up (for a lack of a better term) like such: puts comments[0][1].to_a #<Comment:0x007fda3b1911b8> {} #<Comment:0x007fda3b190fd8> {}
I'm using Postgres, and I'm using closure_tree's hash_tree to sort the comments. Any advice would be very much appreciated, especially with the first question. EDIT: The def index that returns the comments: def index if request.headers["type"] == 'music' comments = Comment.where("song_id = ?", request.headers["id"]).hash_tree.to_a comments.each do |comment| puts comment[1] #shows all attributes and values puts comment[1].to_a #blows up puts comment[1].to_s #works end end if comments render json: {status:200, success:true, comments:comments} else render json: {status:404, success:false} end end

| My rendering in Rails (possibly) causes a 422 error Posted: 20 Aug 2016 08:19 AM PDT I have received reports from users to my website that they get Error 422 when visiting a "result" page using POST. I cannot re-create this error at all so I am wondering if there is anything in my code below that would cause this error in formatting? I expect there could be errors here since I have upgraded a Rails 3.x project to a Rails 4.2. I would either like to know if there is anything obvious in the code that would create 422 errors or if there is anyway to troubleshoot 422-errors. Basically, in #show there is a POST method to result. It is creating a result text and lands on a url like /this-post-name/result?r=abc123 . I am rendering #show in /result because it is basically loading the same page again but with a "result box". Having to use /result is a choice I made as a newbie programmer and is not absolutely necessary, I think. I am quite sure the error lies within the "respond_to" but can't figure that out, or troubleshoot it (i.e. re-create it). Also, I am not sure if this is important, but I get tons of AuthencityToken errors on this page. Edit: I managed to recreate this issue by accessing it through my iPhone and post a form, then I disabled cookies and send the form again. That would not be something people would do often but I guess having cookies disabled may cause this? def show @avaliable_posts = Post.where(:available => true) end def result if request.get? && params[:r].blank? # Just visiting /result withoutout POST or ?r url redirect_to category_path(@category) else set_round(session[:round_by_number]) # Either the visitor just posted the result or is revisiting through URL if !params[:r].blank? # Visitor arrived from URL @result = Result.find_by_scrambled_identifier(params[:r]) params_to_use = @result.params_used @params_to_use = @result.params_used else params_to_use = params @params_to_use = params_to_use end post_instance = @post.get_post_instance(params_to_use) if post_instance.valid? @post_result_array = post_instance.calculate_me(params_to_use) @post_result_text_array = @post_result_array[0] respond_to do |format| format.html { render :action => "show" } format.json { render :json => @post } end else # post not valid @errors = post_instance.errors respond_to do |format| format.html { render :action => "show" } format.xml { render :xml => @validator.errors, :status => :unprocessable_entity } format.json { render :json => @post } end end end end
